A single rail roller coaster is a roller coaster that only rides on one rail instead of the two that other roller coasters ride on. The most well known manufacturer of single rail roller coasters is Rocky Mountain Construction, but the Pax Company from Russia also manufacture single rail roller coasters. Some of the suspended roller coasters manufactured by Caripro and Setpoint could also class as single rail roller coasters. Rocky Mountain Construction currently offers two models of single rail roller coaster; Raptor Track and T-Rex Track. Raptor Track is a smaller type of track that can only have riders sat inline with one another due to its size, whereas T-Rex Track is larger and can seat 2 riders across. No T-Rex Tracks have currently been announced, but there are two Raptor Tracks that opened in 2018; Wonder Woman Golden Lasso Coaster at Six Flags Fiesta Texas and RailBlazer at California's Great America. A third, Jersey Devil Coaster, opened on June 13, 2021 at Six Flags Great Adventure. A fourth, Stunt Pilot, opened May 29, 2021 at Silverwood theme park. The Skywarps from Skyline Attractions could also be counted as single rail roller coasters. A fifth, Wonder Woman Flight Of Courage will open in 2022 at Six Flags Magic Mountain.
